I think I have the answer. It depends on I (moment of inertia) If I is taken from the point of pivot P then I is including all the efect of the movement of the CM (center of mass). On the other hand, if I is referred to the CM then It is necessary to use ...

I have doubts with KE after the collision. Is posible that in \frac{1}{2}Mv_{cm}^2+\frac{1}{2}I\\w^2 = Mga(\sqrt{2}-1) The term \frac{1}{2}Mv_{cm}^2 is OK? or It's enough with \frac{1}{2}I\\w^2 = Mga(\sqrt{2}-1)? I am not clear so some help would be great

Hi everybody some help needed here! A cube, mass M move with v0 collide with small object "fixed" to the surface in Point P that make it pivot over its side So far I think I understand: During the impact there is no conservation of KE L Angular Momentum : there is an unknown force F...
